Pourkhabbaz, Hamid Reza | Mohammadyari, Fatemeh | Aghdar, Hossein | Tavakoly, Morteza
Study of changes in the past and the destruction of resources and the feasibility and expected changes in the coming years can be planning and optimal use of resources and controlling non-fundamental changes in the future is an important step. The present study aimed to model the Behbahan using LCM city land use changes and Markov chain was used. In this regard, land use change detection using satellite images Landsat, ASTER and ETM+ (Image 2000) and OLI (Image 2014) was performed. Using logistic regression modeling and 6 variable power transmission, digital elevation models, slope, away from residential areas, the distance of agricultural, away from the road map and Evidence Likelihood was performed. For maps of the distance from residential areas, agricultural lands and away from the road distance analysis Euclidean distance and to evaluate the correlation between the independent variables and the dependent variable Cramer's correlation coefficient was used. The ROC indicator used to assess the validity of the model. Comparison of modeled area map with the map of 2014 shows the residential areas and agricultural land continues to be a growing trend will continue. As the residential area of 3157 hectares, 4180 hectares in 2014 to 15030 hectares to 20778 hectares of agricultural land increased. But the destruction of rangeland has not only not improved, but the intensity is much higher than the last.

Hajizadeh, Fatemeh | Mirkarimi, Seyed Hamed | Salman Mahiny, AbdolRasoul | Mohammadzadeh, Marjan
Today, with the rapid growth of urban population and as a result, rapid and unbridled urbanization of human societies have been caused some issues. In Gorgan, an increase in level of urban settlements is done regardless to the capabilities and limitations of land and ecological potential of urban development. In this study, it is performed to evaluate and conform to urban development, regard to ecological capability to protect the environmental ability of Grogan. In this case, the multi-criteria assessment approach with weighted linear combination of the GIS is performed to evaluate the ecological capability of Gorgan for conformity to urban development in different years based on the criteria. Then, there is a comparison between final map of capability and current development; moreover, the rate of conformity in different years is calculated. It is illustrated that the ecological conformity had been decrease gradually from 1987 to 2013, which causes hazardous effects on the environment that seems to be still remain for years. Therefore, reduction of the ecological noncompliance should be considered by relevant authorities. The outputs could be used for urban planners to observe the environmental principles to promote existing conditions.

2015
Robati, Maryam
Quantifying the performance of national policies and programs in different economic, social, and environmental fields has always been a major concern of planners, politicians and researchers worldwide. According to UN statistics, more than 60% of the world population will live in urban areas by the year 2030Despite occupying only 2% of the total land area on Earth, more than half the world's population is living in cities. In this study, a systems approach was adopted to develop a composite index in order to assess the potential of a city to become sustainable. The index is composed of 10 components containing a total number of 19 indicators. According to which, the 22 districts of Tehran City were compared in terms of sustainability of urban environment quality. The obtained results indicated that the Districts 1, 2 and 3 are in ideal sustainability conditions. These areas are among prosperous places of the city. About 59.09% of all districts were below the average. The Districts 18 and 19 with the values of 0.21 and 0.25 remain in critical condition.

Safiisabet, Naser | Esmaailzadeh, Hassan
During last two decades, rural-urban linkages in the form of regional interaction networks have been analyzed particularly in the geographical literature. In respect to economic linkages, periodic markets network could be assumed as one of the most important markets. In the sustainable social- economic conditions, this can result in positive and reciprocal functions. This study aims to determine the role of periodic markets network in regional development around Tehran metropolis. In this descriptive-analytical research, 199 sellers and 384 buyers in 49 periodic markets surrounding Tehran Metropolis were studied. To measure the effective factors in the establishment of periodic markets network and regional development, five indicators such as population size, share of urban wholesalers, share of urban and rural street vendors, share of agricultural and non-agricultural products and share of intra-area and regional transportation network were chosen. Results showed that population size and the convergent role of rural and urban street vendors associated with the development of intra-area transportation network were effective in the establishment and sustainability of rural and urban periodic markets network and regional development. It is proposed to note promoting share of direct supply of rural agricultural and non-agricultural products to these markets for rural- urban balanced development.

Hoseini, Seyed Hadi | Sedigi, ABbolfazl
Spatial planning concept refers to alignment and arrangement of relationship between people, space and activities at different geographical scales with emphasis on the role of decision-making and decision-taking. Objective of this research is investigating the spatial distribution and localization of therapeutic land use (important hospitals) of Mashhad city with passive defense approach. Although, emphasis is on passive defense approach, however, because it is closely tied to the issue of spatial planning (especially in urban scale), the findings of the study can also be effective in spatial planning and urban planning. Study area is city of Mashhad that with regard to the diversity of therapeutic spaces, major city hospitals were selected for final consideration. Research methodology is descriptive - analysis method. Findings of Research indicate that the main part of important hospitals in Mashhad have been concentrated in the central part of the city. These regions located in areas of high risk in terms of passive defense. Imbalance between density population and spatial distribution of hospitals in urban areas is strongly noticeable. Finally, with attention to investigations and results, some suggestions for reduction hazards of therapeutic spaces in times of crisis offered.
